Embodiment Construction

[0016] Such as figure 1 As shown, the cavity-type automatic different body reversing mechanism of the present invention includes A cylinder, B cylinder, reversing valve A and reversing valve B, and the structure of the A cylinder and B cylinder is the same, and the reversing valve A and the reversing valve B has the same structure;

[0017] The structure of cylinder A is as follows: it includes three cylinders, and the three cylinders are connected together in turn to form six chambers, which are chamber I, chamber II, chamber III, chamber IV, chamber V and chamber VI in sequence. Both chamber II and chamber V are hollow, and the pistons of the three cylinders are connected together by a piston rod, so that the three pistons are linked;

[0018] Both the A cylinder and the B cylinder are provided with a slide block 1, and the top of the slide block is provided with a protrusion 2, and the slide block 1 is pushed to move left and right by the pistons on both sides of the A cyl...

Abstract

The invention discloses a cavity type automatic special-shaped body reversing mechanism and belongs to the technical field of automatic reversing of oil cylinders. According to the cavity type automatic special-shaped body reversing mechanism, a special-shaped body is adopted for reversing, a dead point is prevented from being generated, a connecting rod makes a boss move under the control of a hydraulic cylinder piston, and then a two-position four-way reversing valve is controlled to act. According to the technical scheme, the cavity type automatic special-shaped body reversing mechanism is characterized in that an A cylinder and a B cylinder are respectively provided with a cavity I, a cavity II, a cavity III, a cavity IV, a cavity V and a cavity VI in sequence, the cavities II and the cavities V are all hollow, pistons of three cylinder bodies of the A cylinder are connected through a piston rod, so that linkage of the three pistons is achieved, and pistons of three cylinder bodies of the B cylinder are connected through a piston rod, so that linkage of the three pistons is achieved; sliding blocks are arranged on the A cylinder and the B cylinder, protrusions are arranged on the tops of the sliding blocks, the sliding blocks are pushed by the pistons located on the two sides of the A cylinder and the B cylinder to move leftwards and rightwards, and the protrusions move leftwards and rightwards to shift a reversing valve A and a reversing valve B to achieve reversing. The cavity type automatic special-shaped body reversing mechanism can be widely applied to the field of hydraulic automatic reversing.

Description

technical field [0001] The invention discloses a cavity-type automatic different-body reversing mechanism, which belongs to the technical field of oil cylinder automatic reversing. Background technique [0002] China is a large coal-producing country, a country that relies heavily on coal energy, and is also a country with a large number of mining disasters. The main causes of mining disasters are man-made reasons such as illegal mining of coal mines, production errors, equipment aging and malfunctions. [0003] When coal mines are mined underground, due to the possibility of gas leakage during the mining process, the gas mixes with air, oxidizes rapidly at high temperature, and forms a shock wave phenomenon. China's coal mine gas explosions are mainly electric sparks and blasting, and the main place is the mining face , the instantaneous temperature generated by the gas explosion is high, the pressure expands quickly, and the gas near the explosion element impacts outward a...
